Salinity of soil and irrigation water is one of the major concern for crop production under salt-affected arid and semi-arid areas of the world. Using beneficial plant growth promoting microorganisms such as plant symbiotic fungi and plant growth promoting bacteria can be an implement in alleviating deleterious effect of salinity. In this regards, a greenhouse experiment was conducted out in 2012 to investigate the effects of salinity irrigation (low, mild, high and severe) and Piriformospora indica inoculationon grain yield and some physiological traits of wheat under interference with wild oat weed (Avena ludoviciana L.). Experimental disgn was factorial arranged in randomized complete block with three replications. P. indica increased grain yield of wheat under both non-salinity and salinity conditions. Wheat plants in sole culture and in interference with wild oat weed had higher grain P content, proline accumulation and chlorophyll content of leaf. In conclusion, P. indica sustained or improve grain yield of salt-stressed wheat under competition with wild oat through improvement of P uptake, proline accomulation and chlorophyll content. Result of this study showed that inoculation seed of wheat with P. indica may be considered as a new method to manage crop-weed interference under salt-affected areas.
